tf = isaUnderlying(X,cl) returns
a tall array containing logical 1 (true)
if the underlying data in tall array X is of class cl.
Otherwise, the tall array contains logical 0 (false).
All tall tables and arrays belong to the tall class. However, the underlying data type of a tall array can vary.
Create a datastore for the airlinesmall.csv data set. Select a subset of the variables to work with, and treat 'NA' values as missing data so that datastore replaces them with NaN values. Convert the datastore into a tall table.
